An oscillator comprising a compensation circuit, an oscillating module and a controller are disclosed. The compensation circuit comprises a charging circuit and a discharging circuit. The charging circuit comprises a first current source coupled between a voltage source and a second transistor, and the second transistor having a second first terminal coupled to a first current source, a second second terminal coupled to a first node, and a second gate for receiving a first switching signal. The discharging circuit comprises a third transistor having a third first terminal coupled to the first node and a third gate for receiving a second switching signal, and a second current source coupled between the third transistor and ground. The oscillating module couples between the compensation circuit and the controller and generates an output signal. The controller generates the first switching signal and the second switching signal according to the output signal.
